Release Notes for v3.7.21 (296729) - Second Life Viewer

Release Notes

This release adds some fixes to previously released changes in the way we handle joint offsets in rigged meshes. Originally, if you attached multiple meshes with joint offsets, the results were unpredictable, depending on the order in which the attachments were processed. This means that you could see yourself with different joint positions at different times, and the way you saw yourself might not match up to what others saw. With these changes, the behavior is deterministic, so wearing the same set of meshes should always produce the same joint positions, and the way you see yourself should consistently match the way others will see you.The process for removing attached meshes is also more robust, so you should be able to reliably get your old joint positions back after meshes are removed. People running un-updated viewers will continue to see the original behavior with the original bugs, but will not experience any new regressions due to these changes.

This release also fixes some issues found with adding and removing attachments after the recent AISv3 deploy, and improves the status information shown in inventory for attached objects.
